OMSAS GPA Scale Explained

OMSAS doesn’t use your university’s raw grades directly — every course is converted to a standardized 4.0 scale using the OMSAS Undergraduate Grade Conversion Table. The exact cutoffs vary slightly depending on which of the nine OUAC conversion scales your school uses, but most Ontario universities fall under the percentage-based scale below.

Note: OMSAS maps each university to one of nine official conversion scales, so exact percentage cutoffs can differ slightly by school. Use this table as a general guide, and check the official OUAC Undergraduate Grade Conversion Table for your specific institution before finalizing your application.

Your OMSAS cumulative GPA isn’t a simple average of your converted grades — it’s weighted by course length:

– Full-year course = weight of 2
– One-semester course = weight of 1
– Three-quarter course = weight of 1.5
– Lab-only course = weight of 0.5

The formula OMSAS uses is:

Cumulative GPA = (Σ course weight × converted grade) ÷ (Σ course weights)

In plain terms: multiply each course’s converted grade by its weight, add those all together, then divide by the total of all the weights — not by the number of courses.

What Counts Toward Your OMSAS GPA

OMSAS calculates your GPA using every university-level undergraduate credit course you’ve taken at a Canadian or American university — including courses beyond your degree requirements. This includes:

– Repeated courses (both your original and repeat grades)
– Failed courses
– Incomplete and supplemental courses

The following do NOT count toward your OMSAS GPA:

– Graduate-level courses, or undergraduate courses taken as part of a graduate program
– College-level courses, even if you received transfer credit for them
– Courses graded Pass/Credit (though Fail grades still count)
– Challenge-for-credit courses
– Continuing education courses
– Professional program courses (e.g., naturopathic medicine, chiropractic medicine, Doctor of Medicine)
– Consecutive Bachelor of Education degrees
– AP and IB credits
– International transcripts (these are assessed separately and are non-convertible)

How OMSAS Weighs Your Courses

Because course length varies, OMSAS doesn’t treat every course equally when calculating your cumulative average. A full-year course carries twice the weight of a one-semester course, and lab components are weighted lightly on their own. See the formula above for exactly how these weights combine — this is also why simply averaging your semester or yearly GPAs together produces a different (and less accurate) number than OMSAS’s actual calculation.

How Repeated and Failed Courses Affect Your GPA

This trips up a lot of applicants: if you repeated a course, OMSAS includes BOTH your original grade and your repeat grade in your cumulative GPA — it does not drop or replace the first attempt, even if your home university’s own GPA recalculation policy does. The same applies to failed courses: an F stays in your OMSAS GPA calculation permanently, even after you’ve successfully retaken and passed the course. Applicants who assume a strong repeat grade “erases” a bad one are often surprised by their calculated OMSAS GPA.

Common Mistakes When Calculating Your OMSAS GPA

1. Averaging yearly GPAs instead of using the weighted formula. If your course load or mix of full-year/semester courses changed year to year, averaging your yearly GPAs together will not match OMSAS’s actual weighted calculation.

2. Assuming a repeated course replaces the original grade. OMSAS counts both attempts — see above.

3. Including courses that don’t actually count. Pass/Credit courses, AP/IB credits, and college-level courses (even with transfer credit) are excluded, but applicants often include them by mistake.

4. Using the wrong grade conversion scale. Your university maps to one specific OUAC conversion scale — using a generic percentage-to-4.0 chart instead of your school’s actual scale can throw off your number.

5. Forgetting to include courses outside your major or degree requirements. OMSAS counts every eligible undergraduate course you’ve taken, not just the ones required for your program.

Frequently Asked Questions

What GPA scale does OMSAS use?

OMSAS converts all your grades to a 4.0 scale using its Undergraduate Grade Conversion Table, which maps your specific university's grading scale to a standardized OMSAS value between 0.00 and 4.00.

Does OMSAS GPA calculation include failed courses?

Yes. Failed courses are included in your cumulative GPA calculation, along with incomplete and supplemental courses.

What happens to my GPA if I repeat a course?

OMSAS includes both your original grade and your repeat grade in the calculation — it does not replace or drop the first attempt, even if your university's own GPA recalculation policy does.

Do AP, IB, or college transfer credits count toward my OMSAS GPA?

No. AP and IB credits, as well as college-level courses (even with transfer credit to a university), are excluded from the OMSAS GPA calculation.

How is my cumulative OMSAS GPA calculated if my course load changes each year?

OMSAS uses a single weighted formula across your entire undergraduate record — multiplying each course's converted grade by its weight (2 for full-year, 1 for one-semester, 1.5 for three-quarter, 0.5 for lab) and dividing by the total weights — rather than averaging separate yearly GPAs together.
